How much sleep did you get last night? If you live in Kansas, where current stress levels are high, there is about a 30 percent chance that it was less than seven hours and not enough for a body to recharge all its parts.

The Centers for Disease Control and Prevention and World Health Organization have made it official: Sleep deprivation is a public health problem. Fifty years ago, Americans slept 1 to 1 1/2 hours more than they do today. Some might be proud of accomplishing more in a day and sleeping less, but they should consider how the body deprives itself of crucial processes when that happens.
